Fasting is the willful refrainment from eating and sometimes drinking.

From a purely physiological context, “fasting” may refer to the metabolic status of a person who has not eaten overnight, or to the metabolic state achieved after complete digestion and absorption of a meal.

Researchers suggest that fasting may help boost cognitive performance, protect from obesity and associated chronic diseases, reduce inflammation, improve overall fitness, support weight loss, and decrease the risk of metabolic diseases.

However, when you do fasting longer than 24 hours, and particularly three or more days, you should only do it under the supervision of a health professional and preferably in a live-in clinic.
